All of the Apple-lovers in your life have a reason to be happy today, as this is the Launch Day of Valve Software’s Steam platform for Mac (which we’ve been anxiously awaiting for 3 months!).  Not only the game distribution platform, but some of their most popular games.  On launch (today) they have Portal, and a 3rd party title named Torchlight.  They plan to release new games every Wednesday as they continue to port their library of games to the new platform.  But games aren’t the only thing:

In addition to bringing the online functionality of Steam to the Mac, Valve will also make its Steamworks suite of publishing and development tools available on the Mac platform. These include product key authentication, copy protection, auto-updating, social networking, matchmaking, anti-cheat technology, and more. The features and services available in Steamworks are offered free of charge and may be used for both electronic and tangible versions of games.
